Replacing a template

In the plug-in manifest editor, add an extension for the org.skyway.core.jetArtifactDefinitionSet extension point.
Select the (set) child node (this was automatically added for you) and enter the id of the artifact set you want to contribute to. The artifact set for the Skyway web deployment facet is org.skyway.integration.java.spring.artifactset.
Right click this (set) node and choose New/override.
Enter the original template of the artifact you are overriding. Every Skyway artifact is generated using JET and all have unique templates, so any artifact can be precisely overridden by specifying its original template path.
Define the new artifact definition. See Adding an artifact for details.
